Facebook allows advertisers to target iOS IDs in Custom Audiences

Included in the newest round of Facebook updates for developers is a new software development kit (SDK) for iOS in line with iOS 7 and an official announcement about the new image specs in links. Facebook also announced that advertisers can reach mobile customers by leveraging iOS identifier for advertising (iOS IDFAs).

Facebook notes that advertisers can upload a list of existing customers’ iOS iDFAs and reach them with relevant content. This will be possible for any user on iOS 6 or 7 who has not disabled advertising tracking.
